Answer: 2572.44

V=(4/3)πr^3 (the formula for volume of sphere)

plug in 17/2 for r  (17 is the diamater and r is the radius which is half of the diamater)

Put this in calc

(4/3)π17/2^3

You get 2572.44

hundredth =175.95cm

Area=3.142×r^2

A= 3.142×28^2=2463.328

Step-by-step explanation:

C) True

D) False Solution is actually (-3, -3)

work below

Note: Used Elimination Method

Multiply the first equation by -2,and multiply the second equation by 1.

−2(−2x+y=3)

1(3x+2y=−15)

Becomes:

4x−2y=−6

3x+2y=−15

Add these equations to eliminate y:

7x=−21

Then we solve 7x = −21 for x:

7x = −21

7         7

(we Divide both sides by 7)

x=−3

Now that we've found x let's put it back in to solve for y.

Put down an original equation:

−2x+y=3

Substitute−3 for x in−2x+y=3:

(−2)(−3)+y=3

y+6=3(Simplify both sides of the equation)

y+6+−6=3+−6(Add -6 to both sides)

y= −3

Solution

(-3, -3)

Answer:

[tex]y = \frac{5}{2}x-1[/tex]  

Step-by-step explanation:

Slope-intercept form is represented by the formula [tex]y = mx + b[/tex]. So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:

[tex]5x-2y = 2\\-2y = -5x + 2\\\frac{-2}{-2}y = \frac{-5}{-2} x+\frac{2}{-2} \\y = \frac{5}{2} x-1[/tex]

So, the slope-intercept form is [tex]y = \frac{5}{2}x-1[/tex].

Step-by-step explanation:

Answer:

Step-by-step explanation:

so we can make a system of equations

y=hotdogs

x=hamburgers

you need a combination that sums to 23, so add the two and get 23:

y+x=23

and then you need to account for how much money you have and the cost.

1.50x+1.10y=32.10

still working on it, will edit in rest so that you can see what I did

Step-by-step explanation:

Answer:

E. 1d+0.015d

G. 1.015d

Step-by-step explanation:

A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.

Answer:

Step-by-step explanation:

Length of each side = √(169/36)

= √169/√36

= 13/6 yards

Perimeter = 4(13/6) = 26/3 yards

Perimeter of the flower bed is 26 / 3  yards

Given:

[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\[/tex]

Find:

Perimeter of the flower bed

Computation:

Area of square = side²

So,

[tex]Area\ of\ square\ flower\ bed\ = \frac{169}{13} square\ yard\\\\Side^2 = \frac{169}{36} \\\\Side^2 = [\frac{13}{6}]^2 \\\\Side = \frac{13}{6} \ yard[/tex]

Perimeter of square = 4(Side)

[tex]Perimeter\ of\ the\ flower\ bed = 4(\frac{13}{6} ) \\\\Perimeter\ of\ the\ flower\ bed = \frac{26}{3} \ yards[/tex]

Answer:

Sketch of a cube with side = 4 in as shown.

The shaded area is perpendicular to the right and left vertical faces of the cube, so the cross section is a square with each side equal to 4 in.

The area of the cross section is

4*4 = 16 in²

The perimeter of the cross section is

4+4+4+4 = 16 in.

Answer:

120 cm, 160 cm, 80 cm, 360 cm

Step-by-step explanation:

The ratio 3:4:2:9 is the same as the ratio 3x:4x:2x:9x

We add all the terms of the second ratio:

3x + 4x + 2x + 9x = 18x

18x = 720

x = 40

3x = 3(40) = 120

4x = 4(40) = 160

2x = 2(40) = 80

9x = 9(40) = 360

Answer: 120 cm, 160 cm, 80 cm, 360 cm

Hello There!

To find the slope we can use the slope formula

let m = slope

[tex]m = \frac{y_2-y_1}{x_2-x_2}[/tex]

now lets find two points so we can plug the values into the formula

the points chosen is optional but the points i chose were

(5,20) and (15,60)

remember when plugging in the values into the formula we plug in the second ordered pair first so

also remember that the y values go on top and the x values go on the bottom

[tex]m = \frac{60-20}{15-5} \\60-20=40\\15-5=10\\m=\frac{40}{10} or 4[/tex]

So we can conclude that the slope of the line is 4

Answer:

|5 - 7| =2

What you want to do first is to do the equation 5-7 which is -2 but there is an absolute value sign so 2.

-3|11 - 15|=-12

For this one it is a little more difficult but all you have to do is do the equation 11-15 which is -4 but there is an absoulte value sign so 4 you then multiply 4 by -3 which is -12 bam.

Answer:

Step-by-step explanation:

You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.

6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23.  Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.

Answer:

240.

Step-by-step explanation:

First you need to find out what his monthly payments are (60x24=1440)

Then you would subtract his monthly payments (1440) to the amount that he borrowed for the furniature (1200) which would give you 240.
